摘　　要：为确定出涡流管各因素的主次顺序,找出最优的参数组合,提出正交试验设计和极差分析法,找到涡流管能量分离效应的最优化尺寸参数。实验设定涡流管进气温度为26℃,环境温度为27.1℃,结果表明,4个尺寸参数对涡流管能量分离影响排序为:长径比>喷嘴数目>冷端直径>进气压力,每个参数的最优值各为长径比为25.0、喷嘴个数为6、冷端直径为5 mm、进气压力为0.8 MPa,并通过对试验结果的验证,发现涡流管的冷热端出口温差为95.2℃。根据正交试验设计方案找出了涡流管各部件的最优尺寸参数。In order to determine the primary and secondary order of each factor of the vortex tube and find the optimal parameter combination,the orthogonal test design and range analysis method were proposed to find the optimal size parameters of the energy separation effect of the vortex tube.The inlet temperature of the vortex tube was set to 26℃,while the ambient temperature was 27.1℃.The results indicated that the order of the influence of the four size parameters on the energy separation of the vortex tube is:length-diameter ratio>number of nozzles>cold end diameter>inlet pressure.The optimal values of each parameter are a length-diameter ratio of 25.0,a number of nozzles of 6,a cold end diameter of 5 mm,and an inlet pressure of 0.8 MPa.Through the verification of the test results,it is found that the outlet temperature difference between the cold and hot ends of the vortex tube is 95.2℃.According to the orthogonal test design scheme,the optimal size parameters of each component of the vortex tube were found out.
